1-x=-6x-2\left(5-4x\right)
Multiply both sides of the equation by 2.
1-x=-6x-10+8x
Use the distributive property to multiply -2 by 5-4x.
1-x=2x-10
Combine -6x and 8x to get 2x.
1-x-2x=-10
Subtract 2x from both sides.
-x-2x=-10-1
Subtract 1 from both sides.
-x-2x=-11
Subtract 1 from -10 to get -11.
-3x=-11
Combine -x and -2x to get -3x.
x=\frac{-11}{-3}
Divide both sides by -3.
x=\frac{11}{3}
Fraction \frac{-11}{-3} can be simplified to \frac{11}{3} by removing the negative sign from both the numerator and the denominator.
